Abstract

Improvement of the strength properties of papers made from recycled fibers is one of the important aims in papermaking industries. Current research revealed that higher retention of strength inducing additives through alternative absorption of polymers having opposite charge is one of the promising approaches to obtain such purpose. In this study, treatment of fibers prepared from neutral sulfite semi-chemical papers with cationic starch and anionic CMC was conducted in pH~7, pH~10 and 0. 001 M NaCl suspension. Then, water retention value (WRV) and zeta potential of fiber suspension was measured. Standard hand sheets with 60± 3 g/m2 basis weight were made from untreated and treated pulps. The results have shown that WRV was significantly increased by absorbing of these two water-absorbing polymers. Consecutive changes of zeta potential confirmed charge reversion of fibers surface and sequential absorption of couple polymers. Scanning electron micrographs prepared from the samples of untreated and treated papers presented new changes in the degree of fibers bond area due to the larger absorption of these two reinforcement polymers. Moreover, considerable development in paper mechanical characteristics (tensile, burst and tear indices) proved the success of high absorption of applied bio-polymers.
